TBS Crossfire System with Microcontroller?

Hey,
I want to know is it possible to make tbs crossfire module with Arduino or any kinds of microcontroller for input and output. I could not find any proper documentation about it.

If You tell what "tbs crossfire" means for You....

TBS == Team Black Sheep

To assist the rest of the forum, the TBS Crossfire is a commercial long range radio control system that includes back telemetry.

I want to know is it possible to make tbs crossfire module with Arduino or any kinds of microcontroller for input and output.

Possible ? I dont see why not, if your very familiar with the various technologies in use and very experinced in Arduino, you might get the job done in a year or so.

I could not find any proper documentation about it.

Its a commercial system, you would not expect them to document it to the level that would make it easy to copy.

or maybe this

would help.

If you are talking about the logic part, not the radio part.

TBS comes out of a healthy and vigorous open source heritage and I would hope and expect that working with Crossfire would still be something we all could manage.

ExpressLRS is an open source project for a super long range transmission system in fpv drones hobby and they are using crossfire wire protocol to connect the receiver to the flight controller, as well as radio to the transmitter. EdgeTX and OpenTX are also open source projects which supports crossfire wire protocol and BetaFlight, CleanFlight, EmuFlight, ArduPilot, etc. are flight controller (flight controller == FC is a microcontroller board with gyro and other parts that stabilize aircraft flight) open source projects that also supports crossfire wire protocol to connect with crossfire reserves. It's a bit weird that it is so hard to find any documentation about crossfire wire protocol.

What did TBS say when you asked them ?

I didn't ask them. I'm just trying to say that wire protocol isn't a top secret altho over the air protocol surely is.
